The present invention relates to novel active compound combinations comprising, firstly, at least one known compound of the formula (I) and, secondly, at least one known compound from the class of the tetronic or tetramic acids, which combinations are highly suitable for controlling animal pests such as insects and unwanted acarids. The invention also relates to methods for controlling animal pests on plants and seed, to the use of the active compound combinations according to the invention for treating seed, to a method for protecting seed and last but not least to the seed treated with the active compound combinations according to the invention.

It is already known that compounds of the formula (I)

in which A represents pyrid-2-yl or pyrid-4-yl or represents pyrid-3-yl which is optionally substituted in the 6-position by fluorine, chlorine, bromine, methyl, trifluoromethyl or trifluoromethoxy or represents pyridazin-3-yl which is optionally substituted in the 6-position by chlorine or methyl or represents pyrazin-3-yl or represents 2-chloropyrazin-5-yl or represents 1,3-thiazol-5-yl which is optionally substituted in the 2-position by chlorine or methyl, or A represents a pyrimidinyl, pyrazolyl, thiophenyl, oxazolyl, isoxazolyl, 1,2,4-oxadiazolyl, isothiazolyl, 1,2,4-triazolyl or 1,2,5-thiadiazolyl radical which is optionally substituted by fluorine, chlorine, bromine, cyano, nitro, C₁-C₄-alkyl (which is optionally substituted by fluorine and/or chlorine), C₁-C₃-alkylthio (which is optionally substituted by fluorine and/or chlorine) or C₁-C₃-alkylsulphonyl (which is optionally substituted by fluorine and/or chlorine), or A represents a radical

in which X represents halogen, alkyl or haloalkyl, Y represents halogen, alkyl, haloalkyl, haloalkoxy, azido or cyano and R¹ represents alkyl, haloalkyl, alkenyl, haloalkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, halocycloalkyl, alkoxy, alkoxyalkyl or halocycloalkylalkyl, have insecticidal action (cf. EP 0 539 588, WO 2007/115643 A1, WO 2007/115644 A1 and WO 2007/115646 A1).

Furthermore, it is known that compounds of the formula (II)

in which either R¹¹═CH₃, R¹²═H, R¹³═CH₃, R¹⁴═H, R¹⁵═COOC₂H₅, R¹⁶═OCH₃, n=1, M=N—H or R¹¹═Cl, R¹²═Cl, R¹³═H, R¹⁴═H, R¹⁵═COC(CH₃)₂C₂H₅, R¹⁶═H, n=1, M=O or R¹¹═CH₃, R¹²═CH₃, R¹³═H, R¹⁴═CH₃, R¹⁵═COCH₂—C(CH₃)₃, R¹⁶═H, n=0, M=O or R¹¹═CH₃, R¹²H, R¹³═CH₃, R¹⁴═H, R¹⁵═H, R¹⁶═OCH₃, n=1, M=N—H have insecticidal properties (cf. EP-A-528 156 and EP-915 846).

Accordingly, formula (II) comprises the following compounds of the formula (IIa), common name spirotetramat, (IIb), common name spirodiclofen, (IIc), common name spiromesifen, and (IId), where the compound of the formula (IIa) is present in the cis configuration (cf. EP-A-01523472) or as a mixture of the cis and trans configuration:

These compounds have been disclosed in published patent specifications and scientific publications.

The compounds of the formulae (IIa) and (IIb) are commercially available as individual active compounds in compositions for controlling animal pests. These compounds and compositions have been described in handbooks such as “The Pesticide Manual, 14th edition, C. D. S. Thomlin (Ed.), British Crop Protection Council, Surrey, UK, 2006”, which is hereby incorporated by reference.

The activity of the insecticidal compound of the formula (I) or the active compound from the class of the ketoenols is generally good. However, in particular at low application rates and in the case of certain pests, they do not always meet the demands of agricultural practice, and there is still a need for economically efficient and ecologically safe pest control.

Further demands on insecticidal compounds include the reduction of the dosage rate; a substantial broadening of the spectrum of pests that can be controlled, including resistant pests; increased safety in use; reduced phytotoxicity and thus better tolerance by plants; the control of pests in their different development stages; better behaviour during production of the insecticidal compounds, for example during grinding or mixing, during their storage or during their use; a very advantageous biocidal spectrum, even at low concentrations, with associated good compatibility with warm-blooded organisms, fish and plants, and achievement of an additional effect, for example an algicidal, anthelmintic, avicidal, bactericidal, fungicidal, molluscicidal, nematicidal, plant-activating, rodenticidal or virucidal action.

Further specific demands on insecticidal compounds that are used on vegetative and generative plant propagation material include negligible phytotoxicity when applied to the seed and plant propagation material, compatibility with soil conditions (for example with regard to binding of the compound to the soil), systemic activity in the plant, no negative impact on germination, and efficacy during the life cycle of the pest in question.

The object of the invention is to meet one or more of the demands mentioned above, such as, for example, the reduction of the dosage rate, a broadening of the spectrum of pests that can be controlled, including resistant pests, and in particular the specific demands for the applicability on vegetative and generative plant propagation material.

It has now been found that combinations of at least one compound of the formula (I), with the proviso that 4-{[(6-chloropyrid-3-yl)methyl](methyl)amino}furan-2(5H)-one and 4-{[(6-chloropyrid-3-yl)methyl] (cyclopropyl)amino}furan-2(5H)-one are excluded, and at least one compound of the formula (II) are synergistically active and are suitable for controlling animal pests.

Surprisingly, the insecticidal and acaricidal action of the active compound combinations according to the invention considerably exceeds the total of the actions of the individual active compounds. A true synergistic effect which could not have been predicted exists, not just a complementation of action.

The synergistic action of the active compound combinations according to the invention of a compound of the formula (I) and an active compound from the class of the ketoenols broadens the range of action of the compound of the formula (I) and the active compound from the class of the ketoenols primarily by a reduction of the dosage rate and by broadening the spectrum of pests that can be controlled. Thus, using the active compound combination according to the invention of a compound of the formula (I) and an active compound from the class of the ketoenols, it is still possible to achieve a high degree of pest control, even in cases where the individual compounds of the active compound combinations according to the invention have only insufficient activity at the low application rates used.

In addition to the synergistic action described above, the active compound combinations according to the invention may show other surprising advantages including increased safety in use; reduced phytotoxicity and thus better tolerance by plants; the control of pests in their different development stages; better behaviour during production of the insecticidal compounds, for example during grinding or mixing, during their storage or during their use; a very advantageous biocidal spectrum even at low concentrations, with associated good compatibility with warm-blooded organisms, fish and plants; and achievement of an additional effect, for example an algicidal, anthelmintic, avicidal, bactericidal, fungicidal, molluscicidal, nematicidal, plant-activating, rodenticidal or virucidal action.

Furthermore, surprisingly, it has been found that the active compound combinations according to the invention are particularly suitable for protecting seed and/or seedlings and leaves from a plant grown from the seeds against damage by pests. Thus, the active compound combinations according to the invention have negligible phytotoxicity when applied to the plant propagation material, compatibility with soil conditions (for example with regard to binding of the compound to the soil), systemic activity in the plant, no negative impact on germination, and efficacy during the life cycle of the pest in question.

The active compound combinations according to the invention comprise, in addition to at least one compound of the formula (I), at least one compound of the formula (II). The active compound combinations according to the invention preferably comprise exactly one compound of the formula (I) and exactly one compound of the formula (II). Preference is furthermore given to active compound combinations comprising one compound of the formula (I) and two compounds of the formula (II). Preference is furthermore given to mixtures comprising two compounds of the formula (I) and one compound of the formula (II).

The compounds of the formula (I) or the active compounds from the class of the tetronic and tetramic acids with at least one basic centre are capable of forming, for example, acid addition salts, for example with strong inorganic acids such as mineral acids, for example perchloric acid, sulphuric acid, nitric acid, nitrous acid, a phosphorus acid or a hydrohalic acid, with strong organic carboxylic acids such as unsubstituted or substituted, for example halogen-substituted, C₁-C₄-alkanecarboxylic acids, for example acetic acid, saturated or unsaturated dicarboxylic acids, for example oxalic acid, malonic acid, succinic acid, maleic acid, fumaric acid and phthalic acid, hydroxycarboxylic acids, for example ascorbic acid, lactic acid, malic acid, tartaric acid and citric acid, or benzoic acid, or with organic sulphonic acids such as unsubstituted or substituted, for example halogen-substituted, C₁-C₄-alkane or arylsulphonic acids, for example methane or p-toluenesulphonic acid. The compounds of the formula (I) or the active compounds from the class of the ketoenols with at least one acidic group are capable of forming, for example, salts with bases, for example metal salts, such as alkali or alkaline-earth metal salts, for example sodium, potassium or magnesium salts, or salts with ammonia or an organic amine such as morpholine, piperidine, pyrrolidine, a lower mono, di or trialkylamine, for example, ethyl, diethyl, triethyl or dimethylpropylamine, or a lower mono, di or trihydroxyalkylamine, for example mono, di or triethanolamine. Moreover, if appropriate, it may also be possible for corresponding internal salts to be formed. In the context of the invention, agrochemically advantageous salts are preferred. With a view to the close relationship between the compounds of the formula (I) or the active compounds from the class of the ketoenols in free form and in the form of their salts, each reference above and below to the free compounds of the formula (I) or free active compounds from the class of the ketoenols or to their salts is meant to be understood such that this also includes the corresponding salts and the free compounds of the formula (I) or the free active compounds from the class of the ketoenols, respectively, if this is applicable and expedient. This also applies in a corresponding manner to tautomers of the compounds of the formula (I) and the active compounds from the class of the ketoenols and to their salts.

In the context of the present invention, the term “active compound combination” refers to various combinations of compounds of the formula (I) and active compounds from the class of the tetronic and tetramic acids, for example in the form of a single ready-mix, in a combined spray mixture composed of separate formulations of the individual active compounds, for example a tank-mix or in a combined use of the individual active compounds in the case of their sequential application, for example in succession within an appropriate short period of time of, for example, a few hours or days. According to a preferred embodiment the order of the application of the compounds of the formula (I) and the active compounds from the class of the tetronic and tetramic acids is not critical for the practice of the present invention.

When using the active compound combinations according to the invention as insecticides and acaricides, the application rates can be varied within a relatively wide range, depending on the kind of application. The application rate of the active compound combinations according to the invention is when treating plant parts, e.g. leaves: from 0.1 to 10,000 g/ha, preferably from 10 to 1,000 g/ha, particularly preferably from 50 to 300 g/ha (when the application is carried out by watering or dripping, it may even be possible to reduce the application rate, in particular when inert substrates such as rock wool or perlite are used); when treating seed: from 2 to 200 g per 100 kg of seed, preferably from 3 to 150 g per 100 kg of seed, particularly preferably from 2.5 to 25 g per 100 kg of seed, very particularly preferably from 2.5 to 12.5 g per 100 kg of seal; when treating the soil: from 0.1 to 10,000 g/ha, preferably from 1 to 5,000 g/ha.

These application rates are mentioned only by way of example and are not limiting in the sense of the invention.

The active compound combinations according to the invention can be employed for protecting plants for a certain period of time after treatment against attack by the animal pests mentioned. The period for which protection is provided extends generally for 1 to 28 days, preferably for 1 to 14 days, particularly preferably for 1 to 10 days, very particularly preferably for 1 to 7 days after the treatment of the plants with the active compounds, or for up to 200 days after a seed treatment.

The active compounds can be converted into the customary formulations, such as solutions, emulsions, wettable powders, water- and oil-based suspensions, powders, dusts, pastes, soluble powders, soluble granules, granules for broadcasting, suspoemulsion concentrates, natural compounds impregnated with active compound, synthetic substances impregnated with active compound, fertilizers and also microencapsulations in polymeric substances.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, i.e. liquid solvents, and/or solid carriers, optionally with the use of surfactants, i.e. emulsifiers and/or dispersants, and/or foam formers. The formulations are produced either in suitable plants or else before or during application.

Suitable for use as auxiliaries are substances which are suitable for imparting to the composition itself and/or to preparations derived therefrom (for example spray liquors, seed dressings) particular properties such as certain technical properties and/or also particular biological properties. Typical auxiliaries include: extenders, solvents and carriers.

Suitable extenders are, for example, water, polar and nonpolar organic chemical liquids, for example from the classes of the aromatic and non-aromatic hydrocarbons (such as paraffins, alkylbenzenes, alkylnaphthalenes, chlorobenzenes), the alcohols and polyols (which, if appropriate, may also be substituted, etherified and/or esterified), the ketones (such as acetone, cyclohexanone), esters (including fats and oils) and (poly)ethers, the unsubstituted and substituted amines, amides, lactams (such as N-alkylpyrrolidones) and lactones, the sulphones and sulphoxides (such as dimethyl sulphoxide).

If the extender used is water, it is also possible to employ, for example, organic solvents as auxiliary solvents. Essentially, suitable liquid solvents are: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols such as butanol or glycol and also their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethyl sulphoxide, and also water.

According to the invention, a carrier is a natural or synthetic, organic or inorganic substance which may be solid or liquid and with which the active compounds are mixed or bonded for better applicability, in particular for application to plants or plant parts or seed. The solid or liquid carrier is generally inert and should be suitable for use in agriculture.

Suitable solid or liquid carriers are:

for example ammonium salts and natural rock flours, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and synthetic rock flours, such as finely divided silica, alumina and silicates; useful solid carriers for granules include: for example, crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, and also synthetic granules of inorganic and organic flours, and granules of organic material such as paper, sawdust coconut shells, maize cobs and tobacco stalks; useful emulsifiers and/or foam-formers include: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates and also protein hydrolysates; suitable dispersants are nonionic and/or ionic substances, for example from the classes of the alcohol-POE and/or -POP ethers, acid and/or POP POE esters, alkylaryl and/or POP POE ethers, fat and/or POP POE adducts, POE- and/or POP-polyol derivatives, POE- and/or POP-sorbitan or -sugar adducts, alkyl or aryl sulphates, alkyl- or arylsulphonates and alkyl or aryl phosphates or the corresponding PO-ether adducts. Furthermore, suitable oligomers or polymers, for example those derived from vinylic monomers, from acrylic acid, from EO and/or PO alone or in combination with, for example, (poly)alcohols or (poly)amines. It is also possible to use lignin and its sulphonic acid derivatives, unmodified and modified celluloses, aromatic and/or aliphatic sulphonic acids and also their adducts with formaldehyde.

Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, or else natural phospholipids such as cephalins and lecithins and synthetic phospholipids can be used in the formulations.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic colorants such as alizarin colorants, azo colorants and metal phthalocyanine colorants, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

Other possible additives are perfumes, mineral or vegetable oils which are optionally modified, waxes and nutrients (including trace nutrients), such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

Stabilizers, such as low-temperature stabilizers, preservatives, antioxidants, light stabilizers or other agents which improve chemical and/or physical stability, may also be present.

The active compound content of the use forms prepared from the commercially available formulations may vary within wide limits. The active compound concentration of the use forms is in the range of from 0.00000001 to 97% by weight of active compound, preferably in the range of from 0.0000001 to 97% by weight, particularly preferably in the range of from 0.000001 to 83% by weight or 0.000001 to 5% by weight, and very particularly preferably in the range of from 0.0001 to 1% by weight.

The active compound combinations according to the invention can be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with other active compounds, such as insecticides, attractants, sterilizing agents, bactericides, acaricides, nematicides, fungicides, growth-regulating substances, herbicides, safeners, fertilizers or semiochemicals.

A mixture with other known active compounds, such as herbicides, fertilizers, growth regulators, safeners, semiochemicals, or else with agents for improving the plant properties, is also possible.

When used as insecticides, the active compound combinations according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with synergists. Synergists are compounds which increase the action of the active compounds, without it being necessary for the synergist added to be active itself.

When used as insecticides, the active compound combinations according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with inhibitors which reduce degradation of the active compound after use in the environment of the plant, on the surface of parts of plants or in plant tissues.

The compounds are employed in a customary manner appropriate for the use forms.

All plants and plant parts can be treated in accordance with the invention. Plants are understood here to mean all plants and plant populations, such as desired and undesired wild plants or crop plants (including naturally occurring crop plants). Crop plants can thus be plants which can be obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including the transgenic plants and including the plant varieties which can or cannot be protected by varietal property rights. Parts of plants are to be understood as meaning all above-ground and below-ground parts and organs of plants, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stems, trunks, flowers, fruit-bodies, fruits and seeds and also roots, tubers and rhizomes. The plant parts also include harvested material and also vegetative and generative propagation material, for example fruits, seeds, cuttings, tubers, rhizomes, slips, seed, bulbils, layers and runners.

Treatment according to the invention of the plants and plant parts with the active compound combinations is carried out directly or by allowing the compounds to act on the surroundings, environment or storage space by the customary treatment methods, for example by immersion, spraying, pouring on, drip irrigation, incorporation in the culture substrate, evaporation, fogging, scattering, painting on, injection and, in the case of propagation material, in particular in the case of seeds, also by applying one or more coats.

The following plants may be mentioned as plants which can be treated according to the invention: cotton, flax, grapevine, fruit, vegetables, such as Rosaceae sp. (for example pome fruits such as apples and pears, but also stone fruits such as apricots, cherries, almonds and peaches, and soft fruits such as strawberries), Ribesioidae sp., Juglandaceae sp., Betulaceae sp., Anacardiaceae sp., Fagaceae sp., Moraceae sp., Oleaceae sp., Actinidaceae sp., Lauraceae sp., Musaceae sp. (for example banana plants and banana plantations), Rubiaceae sp. (for example coffee), Theaceae sp., Sterculiceae sp., Rutaceae sp. (for example lemons, oranges and grapefruit); Solanaceae sp. (for example tomatoes), Liliaceae sp., Asteraceae sp. (for example lettuce), Umbelliferae sp., Cruciferae sp., Chenopodiaceae sp., Cucurbitaceae sp. (for example cucumber), Alliaceae sp. (for example leeks, onions), Papilionaceae sp. (for example peas); major crop plants such as Gramineae sp. (for example maize, turf, cereals such as wheat, rye, rice, barley, oats, millet and triticale), Asteraceae sp. (for example sunflower), Brassicaceae sp. (for example white cabbage, red cabbage, broccoli, cauliflower, Brussels sprouts, pak choi, kohlrabi, small radishes, and also oilseed rape, mustard, horseradish and cress), Fabacae sp. (for example beans, peanuts), Papilionaceae sp. (for example soya bean), Solanaceae sp. (for example potatoes), Chenopodiaceae sp. (for example sugar beet, fodder beet, Swiss chard, beetroot); useful plants and ornamental plants in gardens and forests; and in each case genetically modified types of these plants.

The active compound combinations according to the invention are particularly suitable for the treatment of seed. Here, particular mention may be made of the combinations according to the invention mentioned above as preferred or particularly preferred. Thus, most of the damage to crop plants which is caused by pests occurs as early as when the seed is infested during storage and after the seed is introduced into the soil, and during and immediately after germination of the plants. This phase is particularly critical since the roots and shoots of the growing plant are particularly sensitive and even minor damage can lead to the death of the whole plant. Protecting the seed and the germinating plant by the use of suitable compositions is therefore of particularly great interest.

The control of pests by treating the seed of plants has been known for a long time and is the subject of continuous improvements. However, the treatment of seed entails a series of problems which cannot always be solved in a satisfactory manner. Thus, it is desirable to develop methods for protecting the seed and the germinating plant which dispense with the additional application of crop protection products after sowing or after emergence of the plants. It is furthermore desirable to optimize the amount of active compound employed in such a way as to provide optimum protection for the seed and the germinating plant from attack by pests, but without damaging the plant itself by the active compound employed. In particular, methods for the treatment of seed should also take into consideration the intrinsic insecticidal properties of transgenic plants in order to achieve optimum protection of the seed and also of the germinating plant with a minimum of crop protection products being employed.

Accordingly, the present invention also relates in particular to a method for protecting seed and germinating plants against attack by pests by treating the seed with an active compound combination according to the invention. The method according to the invention for protecting seed and germinating plants against attack by pests comprises a method where the seed is treated simultaneously with an active compound of the formula (I) and a compound of the formula (II). It also comprises a method where the seed is treated at different times with an active compound of the formula (I) and a compound of the formula (II). The invention also relates to the use of the active compound combinations according to the invention for treating seed for protecting the seed and the plant arising therefrom against pests. Furthermore, the invention relates to seed treated with an active compound combination according to the invention for protection against pests. The invention also relates to seed treated simultaneously with an active compound of the formula (I and a compound of the formula (II). The invention furthermore relates to seed treated at different times with an active compound of the formula (I) and a compound of the formula (II). In the case of seed treated at different times with an active compound of the formula (I) and a compound of the formula (II), the individual active compounds of the composition according to the invention may be present in different layers on the seed. The layers comprising an active compound of the formula (I) and a compound of the formula (II) may optionally be separated by an intermediate layer. The invention also relates to seed where an active compound of the formula (I) and a compound of the formula (II) are applied as component of a coating or as a further layer or further layers in addition to a coating.

One of the advantages of the present invention is that, because of the particular systemic properties of the active compound combinations according to the invention, treatment of the seed with these compositions not only protects the seed itself, but also the resulting plants after emergence, from pests. In this manner, the immediate treatment of the crop at the time of sowing or shortly thereafter can be dispensed with.

A further advantage is the synergistically increased insecticidal activity of the active compound combinations according to the invention in comparison with the individual insecticidally active compound, which exceeds the expected activity of the two active compounds when applied individually. Also advantageous is the synergistic enhancement of the fungicidal activity of the active compound combinations according to the invention compared with the individual fungicidally active compound, which exceeds the expected activity of the active compound applied individually. This makes possible an optimization of the amount of active compounds employed.

It is likewise to be considered advantageous that the active compound combinations according to the invention can be used in particular also for transgenic seed, where the plants arising from this seed are capable of expressing a protein targeted at pests. By treating such seed with the active compound combinations according to the invention, certain pests can already be controlled by the expression of the for example insecticidal protein and in addition can be protected against damage by the active compound combinations according to the invention.

The active compound combinations according to the invention are suitable for protecting seed of any plant variety as already mentioned above which is employed in agriculture, in the greenhouse, in forests or in horticulture. In particular, this takes the form of seed of maize, peanut, canola, oilseed rape, poppy, soya beans, cotton, beet (for example sugar beet and fodder beet), rice, millet, wheat, barley, oats, rye, sunflower, tobacco, potatoes or vegetables (for example tomatoes, cabbage species). The active compound combinations according to the invention are likewise suitable for treating the seed of fruit plants and vegetables as already mentioned above. The treatment of the seed of maize, soya beans, cotton, wheat and canola or oilseed rape is of particular importance.

As already mentioned above, the treatment of transgenic seed with an active compound combination according to the invention is also of particular importance. This is the seed of the plants comprising generally at least one heterologous gene which controls the expression of a polypeptide having in particular insecticidal properties. The heterologous genes in transgenic seed may originate from microorganisms such as Bacillus, Rhizobium, Pseudomonas, Serratia, Trichoderma, Clavibacter, Glomus or Gliocladium. The present invention is particularly suitable for treating transgenic seed comprising at least one heterologous gene originating from Bacillus sp. and whose gene product shows activity against the European corn borer and/or the Western corn rootworm. Particularly preferably, this is a heterologous gene which originates from Bacillus thuringiensis.

Within the context of the present invention, the active compound combination according to the invention is applied to the seed either alone or in a suitable formulation. Preferably, the seed is treated in a state in which it is stable enough to avoid damage during treatment. In general, the seed may be treated at any point in time between harvest and sowing. The seed usually used has been separated from the plant and freed from cobs, shells, stalks, coats, hairs or the flesh of the fruits.

When treating the seed, care must generally be taken that the amount of the active compound combination according to the invention applied to the seed and/or the amount of further additives is chosen in such a way that the germination of the seed is not adversely affected, or that the resulting plant is not damaged. This must be borne in mind in particular in the case of active compounds which can have phytotoxic effects at certain application rates.

The compositions according to the invention can be applied directly, i.e. without containing any other components and undiluted. In general, it is preferred to apply the compositions to the seed in the form of a suitable formulation. Suitable formulations and methods for treating seed are known to the person skilled in the art and are described, for example, in the following documents: U.S. Pat. No. 4,272,417 A, U.S. Pat. No. 4,245,432 A, U.S. Pat. No. 4,808,430 A, U.S. Pat. No. 5,876,739 A, US 2003/0176428 A1, WO 2002/080675 A1, WO 2002/028186 A2.

The active compounds which can be used in accordance with the invention can be converted into the customary seed-dressing formulations, such as solutions, emulsions, suspensions, powders, foams, slurries or other coating compositions for seed, and also ULV formulations.

These formulations are prepared in a known manner, by mixing the active compounds with customary additives such as, for example, customary extenders and also solvents or diluents, colorants, wetting agents, dispersants, emulsifiers, antifoams, preservatives, secondary thickeners, adhesives, gibberellins and also water.

Colorants which may be present in the seed-dressing formulations which can be used in accordance with the invention are all colorants which are customary for such purposes. In this context, not only pigments, which are sparingly soluble in water, but also dyes, which are soluble in water, may be used. Examples include the dyes known by the names Rhodamine B, C.I. Pigment Red 112 and C.I. Solvent Red 1.

Suitable wetting agents which may be present in the seed-dressing formulations which can be used in accordance with the invention are all substances which promote wetting and which are conventionally used for the formulation of agrochemical active compounds. Preference is given to using alkylnaphthalenesulphonates, such as diisopropyl or diisobutylnaphthalenesulphonates.

Suitable dispersants and/or emulsifiers which may be present in the seed-dressing formulations which can be used in accordance with the invention are all nonionic, anionic and cationic dispersants conventionally used for the formulation of agrochemical active compounds. Preference is given to using nonionic or anionic dispersants or mixtures of nonionic or anionic dispersants. Suitable nonionic dispersants which may be mentioned are, in particular, ethylene oxide/propylene oxide block polymers, alkylphenol polyglycol ethers and tristryrylphenol polyglycol ether, and their phosphated or sulphated derivatives. Suitable anionic dispersants are, in particular, lignosulphonates, polyacrylic acid salts and arylsulphonate/formaldehyde condensates.

Antifoams which may be present in the seed-dressing formulations which can be used in accordance with the invention are all foam-inhibiting substances conventionally used for the formulation of agrochemical active compounds. Silicone antifoams and magnesium stearate can preferably be used.

Preservatives which may be present in the seed-dressing formulations which can be used in accordance with the invention are all substances which can be employed for such purposes in agrochemical compositions. Dichlorophene and benzyl alcohol hemiformal may be mentioned by way of example.

Secondary thickeners which may be present in the seed-dressing formulations which can be used in accordance with the invention are all substances which can be employed for such purposes in agrochemical compositions. Cellulose derivatives, acrylic acid derivatives, xanthan, modified clays and finely divided silica are preferred.

Adhesives which may be present in the seed-dressing formulations which can be used in accordance with the invention are all customary binders which can be employed in seed-dressing products. Polyvinylpyrrolidone, polyvinyl acetate, polyvinyl alcohol and tylose may be mentioned as being preferred.

Gibberellins which can be present in the seed-dressing formulations which can be used in accordance with the invention are preferably the gibberellins A1, A3 (=gibberellic acid), A4 and A7; gibberellic acid is especially preferably used. The gibberellins are known (cf. R. Wegler “Chemie der Pflanzenschutz- and Schädlingsbekämpfungsmittel” [Chemistry of the Crop Protection Compositions and Pesticides], vol. 2, Springer Verlag, 1970, pp. 401-412).

The seed-dressing formulations which can be used in accordance with the invention can be employed for the treatment of a wide range of seed, including the seed of transgenic plants, either directly or after previously having been diluted with water. In this, context, additional synergistic effects may also occur in cooperation with the substances formed by expression.

All mixers which can conventionally be employed for the seed-dressing operation are suitable for treating seed with the seed-dressing formulations which can be used in accordance with the invention or with the preparations prepared therefrom by addition of water. Specifically, a procedure is followed during the seed-dressing operation in which the seed is placed into a mixer, the specific desired amount of seed-dressing formulations, either as such or after previously having been diluted with water, is added, and everything is mixed until the formulation is distributed uniformly on the seed. If appropriate, this is followed by a drying process.

The method of treatment according to the invention can be used in the treatment of genetically modified organisms (GMOs), e.g. plants or seeds. Genetically modified plants (or transgenic plants) are plants in which a heterologous gene has been stably integrated into the genome. The expression “heterologous gene” essentially means a gene which is provided or assembled outside the plant and when introduced in the nuclear, chloroplastic or mitochondrial genome gives the transformed plant new or improved agronomic or other properties by expressing a protein or polypeptide of interest or by downregulating or silencing other gene(s) which are present in the plant (using for example antisense technology, cosuppression technology or RNAi technology [RNA interference]). A heterologous gene that is located in the genome is also called a transgene. A transgene that is defined by its particular location in the plant genome is called a transformation or transgenic event.

Depending on the plant species or plant varieties, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive (“synergistic”) effects. For example, the following effects exceeding the effects actually to be expected are possible: reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the active compounds and compositions which can be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, bigger fruits, larger plant height, greener leaf colour, earlier flowering, higher quality and/or a higher nutritional value of the harvested products, higher sugar concentration within the fruits, better storage stability and/or processability of the harvested products.

At certain application rates, the active compound combinations according to the invention may also have a strengthening effect in plants. Accordingly, they are suitable for mobilizing the defence system of the plant against attack by unwanted phytopathogenic fungi and/or microorganisms and/or viruses. This may, if appropriate, be one of the reasons for the enhanced activity of the combinations according to the invention, for example against fungi. Plant-strengthening (resistance-inducing) substances are to be understood as meaning, in the present context, also those substances or combinations of substances which are capable of stimulating the defence system of plants in such a way that, when subsequently inoculated with unwanted phytopathogenic fungi and/or microorganisms and/or viruses, the treated plants display a substantial degree of resistance to these unwanted phytopathogenic fungi and/or microorganisms and/or viruses. In the present case, unwanted phytopathogenic fungi and/or microorganisms and/or viruses are understood as meaning phytopathogenic fungi, bacteria and viruses. Thus, the substances according to the invention can be employed for protecting plants against attack by the abovementioned pathogens within a certain period of time after the treatment. The period within which protection is brought about generally extends from 1 to 10 days, preferably 1 to 7 days, after the treatment of the plants with the active compounds.

Plants and plant varieties which are preferably treated according to the invention include all plants which have genetic material which imparts particularly advantageous, useful traits to these plants (whether obtained by breeding and/or biotechnological means).

Plants and plant varieties which are also preferably treated according to the invention are resistant against one or more biotic stress factors, i.e. said plants have a better defence against animal and microbial pests, such as against nematodes, insects, mites, phytopathogenic fungi, bacteria, viruses and/or viroids.

Plants and plant varieties which may also be treated according to the invention are those plants which are resistant to one or more abiotic stress factors. Abiotic stress conditions may include, for example, drought, cold temperature exposure, heat exposure, osmotic stress, waterlogging, increased soil salinity, increased exposure to minerals, exposure to ozone, exposure to strong light, limited availability of nitrogen nutrients, limited availability of phosphorus nutrients or shade avoidance.

Plants and plant varieties which may also be treated according to the invention are those plants characterized by enhanced yield characteristics. Enhanced yield in said plants can be the result of, for example, improved plant physiology, growth and development, such as water use efficiency, water retention efficiency, improved nitrogen use, enhanced carbon assimilation, improved photosynthesis, increased germination efficiency and accelerated maturation. Yield can furthermore be affected by improved plant architecture (under stress and non-stress conditions), including early flowering, flowering control for hybrid seed production, seedling vigour, plant size, internode number and distance, root growth, seed size, fruit size, pod size, pod or ear number, seed number per pod or ear, seed mass, enhanced seed filling, reduced seed dispersal, reduced pod dehiscence and lodging resistance. Further yield traits include seed composition, such as carbohydrate content, protein content, oil content and composition, nutritional value, reduction in anti-nutritional compounds, improved processability and better storage stability.

Plants that may be treated according to the invention are hybrid plants that already express the characteristics of heterosis, or hybrid vigour, which results in generally higher yield, increased vigour, better health and better resistance towards biotic and abiotic stress factors. Such plants are typically made by crossing an inbred male-sterile parent line (the female parent) with another inbred male-fertile parent line (the male parent). Hybrid seed is typically harvested from the male-sterile plants and sold to growers. Male-sterile plants can sometimes (e.g. in maize) be produced by detasseling (i.e. the mechanical removal of the male reproductive organs or male flowers) but, more typically, male sterility is the result of genetic determinants in the plant genome. In that case, and especially when seed is the desired product to be harvested from the hybrid plants, it is typically useful to ensure that male fertility in hybrid plants, which contain the genetic determinants responsible for male sterility, is fully restored. This can be accomplished by ensuring that the male parents have appropriate fertility restorer genes which are capable of restoring the male fertility in hybrid plants that contain the genetic determinants responsible for male sterility. Genetic determinants for male sterility may be located in the cytoplasm. Examples of cytoplasmic male sterility (CMS) were for instance described in Brassica species (WO 1992/005251, WO 1995/009910, WO 1998/27806, WO 2005/002324, WO 2006/021972 and U.S. Pat. No. 6,229,072). However, genetic determinants for male sterility can also be located in the nuclear genome. Male-sterile plants can also be obtained by plant biotechnology methods such as genetic engineering. A particularly useful means of obtaining male-sterile plants is described in WO 89/10396 in which, for example, a ribonuclease such as a barnase is selectively expressed in the tapetum cells in the stamens. Fertility can then be restored by expression in the tapetum cells of a ribonuclease inhibitor such as barstar (e.g. WO 1991/002069).

Plants or plant varieties (obtained by plant biotechnology methods such as genetic engineering) which may be treated according to the invention are herbicide-tolerant plants, i.e. plants made tolerant to one or more given herbicides. Such plants can be obtained either by genetic transformation, or by selection of plants containing a mutation imparting such herbicide tolerance.

Herbicide-tolerant plants are for example glyphosate-tolerant plants, i.e. plants made tolerant to the herbicide glyphosate or salts thereof, For example, glyphosate-tolerant plants can be obtained by transforming the plant with a gene encoding the enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). Examples of such EPSPS genes are the AroA gene (mutant CT7) of the bacterium Salmonella typhimurium (Comai et al., Science (1983), 221, 370-371), the CP4 gene of the bacterium Agrobacterium sp. (Barry et al., Curr. Topics Plant Physiol. (1992), 7, 139-145), the genes encoding a petunia EPSPS (Shah et al., Science (1986), 233, 478-481), a tomato EPSPS (Gasser et al., J. Biol. Chem. (1988), 263, 4280-4289) or an Eleusine EPSPS (WO 2001/66704). It can also be a mutated EPSPS, as described, for example, in EP-A 0837944, WO 2000/066746, WO 2000/066747 or WO 2002/026995. Glyphosate-tolerant plants can also be obtained by expressing a gene that encodes a glyphosate oxidoreductase enzyme as described in U.S. Pat. No. 5,776,760 and U.S. Pat. No. 5,463,175. Glyphosate-tolerant plants can also be obtained by expressing a gene that encodes a glyphosate acetyltransferase enzyme as described, for example, in WO 2002/036782, WO 2003/092360, WO 2005/012515 and WO 2007/024782. Glyphosate-tolerant plants can also be obtained by selecting plants containing naturally occurring mutations of the abovementioned genes as described, for example, in WO 2001/024615 or WO 2003/013226.

Other herbicide-resistant plants are for example plants which have been made tolerant to herbicides inhibiting the enzyme glutamine synthase, such as bialaphos, phosphinothricin or glufosinate. Such plants can be obtained by expressing an enzyme detoxifying the herbicide or a mutant glutamine synthase enzyme that is resistant to inhibition. One such efficient detoxifying enzyme is, for example, an enzyme encoding a phosphinothricin acetyltransferase (such as the bar or pat protein from Streptomyces species for example). Plants expressing an exogenous phosphinothricin acetyltransferase have been described, for example, in U.S. Pat. No. 5,561,236; U.S. Pat. No. 5,648,477; U.S. Pat. No. 5,646,024; U.S. Pat. No. 5,273,894; U.S. Pat. No. 5,637,489; U.S. Pat. No. 5,276,268; U.S. Pat. No. 5,739,082; U.S. Pat. No. 5,908,810 and U.S. Pat. No. 7,112,665.

Further herbicide-tolerant plants are also plants that have been made tolerant to the herbicides inhibiting the enzyme hydroxyphenylpyruvatedioxygenase (HPPD). Hydroxyphenylpyruvatedioxygenases are enzymes that catalyse the reaction in which para-hydroxyphenylpyruvate (HPP) is transformed into homogentisate. Plants tolerant to HPPD-inhibitors can be transformed with a gene encoding a naturally-occurring resistant HPPD enzyme, or a gene encoding a mutated HPPD enzyme according to WO 1996/038567, WO 1999/024585 and WO 1999/024586. Tolerance to HPPD-inhibitors can also be obtained by transforming plants with genes encoding certain enzymes enabling the formation of homogentisate despite the inhibition of the native HPPD enzyme by the HPPD-inhibitor. Such plants and genes are described in WO 1999/034008 and WO 2002/36787. Tolerance of plants to HPPD inhibitors can also be improved by transforming plants with a gene encoding an enzyme prephenate dehydrogenase in addition to a gene encoding an HPPD-tolerant enzyme, as described in WO 2004/024928.

Further herbicide-resistant plants are plants that have been made tolerant to acetolactate synthase (ALS) inhibitors. Known ALS inhibitors include, for example, sulphonylurea, imidazolinone, triazolopyrimidines, pyrimidinyl oxy(thio)benzoates, and/or sulphonylaminocarbonyltriazolinone herbicides. Different mutations in the ALS enzyme (also known as acetohydroxy acid synthase, AHAS) are known to confer tolerance to different herbicides and groups of herbicides, as described, for example, in Tranel and Wright, Weed Science (2002), 50, 700-712, and also in U.S. Pat. No. 5,605,011, U.S. Pat. No. 5,378,824, U.S. Pat. No. 5,141,870 and U.S. Pat. No. 5,013,659. The production of sulphonylurea-tolerant plants and imidazolinone-tolerant plants has been described in U.S. Pat. No. 5,605,011; U.S. Pat. No. 5,013,659; U.S. Pat. No. 5,141,870; U.S. Pat. No. 5,767,361; U.S. Pat. No. 5,731,180; U.S. Pat. No. 5,304,732; U.S. Pat. No. 4,761,373; U.S. Pat. No. 5,331,107; U.S. Pat. No. 5,928,937; and U.S. Pat. No. 5,378,824; and also in the international publication WO 1996/033270. Further imidazolinone-tolerant plants have also been described, for example in WO 2004/040012, WO 2004/106529, WO 2005/020673, WO 2005/093093, WO 2006/007373, WO 2006/015376, WO 2006/024351 and WO 2006/060634. Further sulphonylurea- and imidazolinone-tolerant plants have also been described, for example in WO 2007/024782.

Other plants tolerant to imidazolinone and/or sulphonylurea can be obtained by induced mutagenesis, by selection in cell cultures in the presence of the herbicide or by mutation breeding, as described, for example, for soya beans in U.S. Pat. No. 5,084,082, for rice in WO 1997/41218, for sugar beet in U.S. Pat. No. 5,773,702 and WO 1999/057965, for lettuce in U.S. Pat. No. 5,198,599 or for sunflower in WO 2001/065922.

Plants or plant varieties (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are insect-resistant transgenic plants, i.e. plants made resistant to attack by certain target insects. Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such insect resistance.

In the present context, the term “insect-resistant transgenic plant” includes any plant containing at least one transgene comprising a coding sequence encoding:

1) an insecticidal crystal protein from Bacillus thuringiensis or an insecticidal portion thereof, such as the insecticidal crystal proteins compiled by Crickmore et al., Microbiology and Molecular Biology Reviews (1998), 62, 807-813, updated by Crickmore et al. (2005) in the Bacillus thuringiensis toxin nomenclature, (online at: http://www.lifesci.sussex.ac.uk/Home/Neil_Crickmore/Bt/), or insecticidal portions thereof, for example proteins of the Cry protein classes Cry1Ab, Cry1Ac, Cry1F, Cry2Ab, Cry3Ae or Cry3Bb or insecticidal portions thereof; or 2) a crystal protein from Bacillus thuringiensis or a portion thereof which is insecticidal in the presence of a second other crystal protein from Bacillus thuringiensis or a portion thereof, such as the binary toxin made up of the Cy34 and Cy35 crystal proteins (Moellenbeck et al., Nat. Biotechnol. (2001), 19, 668-72; Schnepf et al., Applied Environm. Microb. (2006), 71, 1765-1774); or 3) a hybrid insecticidal protein comprising parts of two different insecticidal crystal proteins from Bacillus thuringiensis, such as a hybrid of the proteins of 1) above or a hybrid of the proteins of 2) above, for example the Cry1A.105 protein produced by maize event MON98034 (WO 2007/027777); or 4) a protein of any one of points 1) to 3) above wherein some, particularly 1 to 10, amino acids have been replaced by another amino acid to obtain a higher insecticidal activity to a target insect species, and/or to expand the range of target insect species affected, and/or because of changes induced in the encoding DNA during cloning or transformation, such as the Cry3Bb1 protein in maize events MON863 or MON88017, or the Cry3A protein in maize event MIR604; or 5) an insecticidal secreted protein from Bacillus thuringiensis or Bacillus cereus, or an insecticidal portion thereof; such as the vegetative insecticidal proteins (VIP) listed at: http://www.lifesci.sussex.ac.uk/home/Neil_Crickmore/Bt/vip.html, for example proteins from the VIP3Aa protein class; or 6) a secreted protein from Bacillus thuringiensis or Bacillus cereus which is insecticidal in the presence of a second secreted protein from Bacillus thuringiensis or B. cereus, such as the binary toxin made up of the VIP1A and VIP2A proteins (WO 1994/21795); or 7) a hybrid insecticidal protein comprising parts from different secreted proteins from Bacillus thuringiensis or Bacillus cereus, such as a hybrid of the proteins in 1) above or a hybrid of the proteins in 2) above; or 8) a protein of any one of points 1) to 3) above wherein some, particularly 1 to 10, amino acids have been replaced by another amino acid to obtain a higher insecticidal activity to a target insect species, and/or to expand the range of target insect species affected, and/or because of changes induced in the encoding DNA during cloning or transformation (while still encoding an insecticidal protein), such as the VIP3Aa protein in cotton event COT 102.

Of course, insect-resistant transgenic plants, as used herein, also include any plant comprising a combination of genes encoding the proteins of any one of the above classes 1 to 8. In one embodiment, an insect-resistant plant contains more than one transgene encoding a protein of any one of the above classes 1 to 8, to expand the range of target insect species affected or to delay insect resistance development to the plants, by using different proteins insecticidal to the same target insect species but having a different mode of action, such as binding to different receptor binding sites in the insect.

Plants or plant varieties (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are tolerant to abiotic stress factors. Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such stress resistance. Particularly useful stress-tolerant plants include the following:

1) Transgenic plants which synthesize a modified starch which is altered with respect to its chemophysical traits, in particular the amylose content or the amylose/amylopectin ratio, the degree of branching, the average chain length, the distribution of the side chains, the viscosity behaviour, the gel resistance, the grain size and/or grain morphology of the starch in comparison to the synthesized starch in wild-type plant cells or plants, such that this modified starch is better suited for certain applications. These transgenic plants synthesizing a modified starch are described, for example, in EP 0571427, WO 1995/004826, EP 0719338, WO 1996/15248, WO 1996/19581, WO 1996/27674, WO 1997/11188, WO 1997/26362, WO 1997/32985, WO 1997/42328, WO 1997/44472, WO 1997/45545, WO 1998/27212, WO 1998/40503, WO 99/58688, WO 1999/58690, WO 1999/58654, WO 2000/008184, WO 2000/008185, WO 2000/28052, WO 2000/77229, WO 2001/12782, WO 2001/12826, WO 2002/101059, WO 2003/071860, WO 2004/056999, WO 2005/030942, WO 2005/030941, WO 2005/095632, WO 2005/095617, WO 2005/095619, WO 2005/095618, WO 2005/123927, WO 2006/018319, WO 2006/103107, WO 2006/108702, WO 2007/009823, WO 2000/22140, WO 2006/063862, WO 2006/072603, WO 2002/034923, EP 06090134.5, EP 06090228.5, EP 06090227.7, EP 07090007.1, EP 07090009.7, WO 2001/14569, WO 2002/79410, WO 2003/33540, WO 2004/078983, WO 2001/19975, WO 1995/26407, WO 1996/34968, WO 1998/20145, WO 1999/12950, WO 1999/66050, WO 1999/53072, U.S. Pat.

The use in the field of domestic insecticides takes place alone or in combination with other suitable active compounds such as phosphoric esters, carbamates, pyrethroids, neonicotinoids, growth regulators or active compounds from other known insecticide classes.

They are used in aerosols, pressure-free spray products, for example pump and atomizer sprays, automatic fogging systems, foggers, foams, gels, evaporator products with evaporator tablets made of cellulose or plastic, liquid evaporators, gel and membrane evaporators, propeller-driven evaporators, energy-free, or passive, evaporation systems, moth papers, moth bags and moth gels, as granules or dusts, in baits for spreading or in bait stations.

The good insecticidal and acaricidal action of the active compound combinations according to the invention can be seen from the examples which follow. While the individual active compounds show weaknesses in the action, the combinations show an action which exceeds a simple sum of actions.

A synergistic effect in insecticides and acaricides is always present when the action of the active compound combinations exceeds the total of the actions of the active compounds when applied individually.

The expected action for a given combination of two active compounds can be calculated according to S. R. Colby, Weeds 15 (1967), 20-22, as follows:

If

X is the kill rate, expressed in % of the untreated control, when the active compound A is used at an application rate of m g/ha or in a concentration of m ppm,

Y is the kill rate, expressed in % of the untreated control, when the active compound B is used at an application rate of n g/ha or in a concentration of n ppm,

E is the kill rate, expressed in % of the untreated control, when the active compounds A and B are used at application rates of m and n g/ha or in a concentration of m and n ppm,

then

$E = {X + Y - \frac{X \times Y}{100}}$

If the actual insecticidal or acaricidal kill rate exceeds the calculated value, the kill of the combination is superadditive, i.e. a synergistic effect is present. In this case, the actually observed kill rate must exceed the value calculated using the above formula for the expected kill rate (E).
